slub: remove invalid reference to list iterator variable
Author: Julia Lawall <Julia.Lawall@lip6.fr> If list_for_each_entry, etc complete a traversal of the list, the iterator variable ends up pointing to an address at an offset from the list head, and not a meaningful structure. Thus this value should not be used after the end of the iterator. The patch replaces s->name by al->name, which is …

driver-core: Move kobj_to_dev from genhd.h to device.h
Author: Lars-Peter Clausen <lars@metafoo.de> This function is not really specific to the genhd layer and there are various re-implementations or open-coded variants of it all throughout the kernel. To avoid further duplications move the function to a more generic place. While moving also convert it from a macro to a inline function. Potential users of …

drivers/ide/ide-cs.c: adjust suspicious bit operation
Author: Julia Lawall <Julia.Lawall@lip6.fr> IO_DATA_PATH_WIDTH_8 is 0, so a bit-and with it is always false. The value IO_DATA_PATH_WIDTH covers the bits of the IO_DATA_PATH constants, so first pick those bits and then make the test using !=. This problem was found using Coccinelle (http://coccinelle.lip6.fr/). Signed-off-by: Julia Lawall Signed-off-by: David S. Miller — drivers/ide/ide-cs.c | 3 …

The value TRIG_ROUND_MASK covers the bits of the TRIG_ROUND constants, so first pick those bits and then make the test using ==. The same is done for TRIG_ROUND_UP for symmetry, even though bit-and would be sufficient in this case. This …
